We talk about “panda bears” and “koala bears,” but for a long time, neither was actually considered a bear species! Koalas are definitely not bears—they’re marsupials, distant cousins of kangaroos and wombats. However, their short faces and rounded ears make them look a little bear-like, hence the nickname.

Pandas are another story. Physically, they have a lot in common with bears, but there are also lots of differences. They eat almost nothing but bamboo, and they have an enlarged bone on their hands that looks like a thumb—characteristics that seem to make them more like red pandas, which are part of the raccoon family. Recent DNA studies, though, have shown that pandas are indeed part of the bear family—they’re just not as closely related to polar bears, grizzlies, and the others as they are to each other!
